Hi Eren,  
 
Thanks for contacting Syncfusion support. 
 
When you are adding a new row using AddNewRow, you can able to listen the adding operation by using CollectionChanged event in SfDataGrid.View. 
 
Please refer the below code example and sample from the given location. 
 
Code Example 
 




public Form1() 
{ 
    InitializeComponent(); 
     
    sfDataGrid.DataSource = data.OrdersListDetails; 
 
    (sfDataGrid.View as CollectionViewAdv).CollectionChanged += CollectionChanged; 
} 
 
void CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) 
{ 
    if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add) 
    { 
        // Do your needed customization here.  
    } 
}

Hi Eren, 
 
Thanks for your update. 
 
We have checked your reported scenario, but we can’t able to reproduce it on our end. We have added the SfDataGrid into an MDI child form. The CollectionChanged event fires when we add a new row. 
 
Please refer the below sample which we are tried to reproduce the issue. 
 
Sample Location: http://www.syncfusion.com/downloads/support/directtrac/general/ze/CollectionChanged_Sample2133997689  
 
If still you have faced the issue, please revert by modifying the attached sample based on your application along with the replication procedure, please share your application if it is possible. It will be helpful for us to analyze further.

You misunderstood me CollectionChanged event fires but another event of mdichildform don't fires (KeyUp,KeyDown etc.)

Not SfDatagrid event or MdiParent event.I am trying to when Press F5 key datagrid's datasource updated or press DELETE selected row deleted

UserControl KeyPress Or Down Event not fired

And i can't set text (title) property of form
Here

public partial class CurrentList : frmList
    {
        public CurrentList(string _title, DataTable dtSource)
        {
            InitializeComponent();
            this.Text = _title;
            sfDataGrid2.DataSource = dtSource;

        }
    }

Hi Eren, 
 
Thanks for your update. 
 
By default, Form will receive all the key events only when enabling the Form.KeyPreview property. You should enable the KeyPreview property of the MDI child form. 
 
Please refer the below MSDN link for further details. 
https://msdn.microsoft.com/en-us/library/system.windows.forms.form.keypreview(v=vs.110).aspx  
 
We have prepared a simple sample with MDI child based on your scenario. Please  refer the sample from the below location.
